Application filed October 27, 1922. Serial No. 597,322.

To aZZ whom t may concern.'

Be it known that I, ALBEN H. VVYATT, a citizen of the United States, residing at Knoxville, in the county of Marion and State of Iowa, have invented certain new and useful Improvements in Photoprint Driers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object of the invention is the provision ot a photo print drier which will save time and labor and'dry the photo print with a. high gloss. i

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

lhile the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without de parting from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is a perspective view of a photo print drier embodying the invention,

Figure 2 is a vertical, central longitudinal section thereof, and

Figure 3 is a vertical transverse section on the line 3 3 of Figure 2.

Corresponding and like parts are referred to in the following description and designated in all the views of the drawings by like reference characters.

The device comprises a box or chamber 1 preferably constructed of sheet metal7 such as galvanized iron, and having an opening in one end which is closed by means of a door 2. An opening 8 is provided in the bottom of the box adjacent an end thereof and this opening constitutes an inlet 'for warm air. An opening 4- is provided in the opposite end of the box in the bottom thereof and constitutes an outlet for the air after having completed a circuit through the box. Corresponding strips 5 are provided along opposite sides of the box and constitute rests to receive and support the squeegee or ferrotype plates on which the prints to be dried are placed. l

A drum 6 is located below the box l is in communication at both ends with the box by means of connections 7 and 8. An opening 9 is provided in the bottom of the drum 6 opposite the opening 4f and is adapted to receive heat from a suitable source, such as a Bunsen burner 10 or any other means of artificial heat. A fan 11 is located in that end of the drum 6 provided with the heat receiving opening 9 and this fan is adapted to be driven by means of an electric motor 12. The heat entering the drum 6 through the opening 9 is driven through the drum by means oi' the tan 11 and enters the box 1 through the opening 3 in the rear of a partition 13, and after circulating through 1the box passes therefrom through the outet f1. the box 1 circulates around the plates placed therein on the rests 5 and not shown and dries the prints thereon quickly by evaporating and carrying off the moisture which escapes through the outlet 4. The partit-ion 13 is spaced a short distance from the rear of The warm air in its passage through the box and terminates short of the top thereof so that the warm air ascending through the space 14 passes over the partition into the upper part of the box, thence downwardly therethrough into the drum 6 through the outlet 4.

at is claimed is:

1. A photo print drier comprising a box having inlet and outlet openings, a drum disposed below the box and in communication at its ends with the inlet and outlet openings thereof, means for supplying hot air to one end portion of the drum, and a fan for causing the hotair to travel through f the drum and into the said box and eifect a positive circulation thereof through the box.

2. A photo print drier comprising a box having inlet and outlet openings, a drum disposed below the box and in communication at its ends with inlet and outlet openings thereof, means for supplying hot air to one end portion ofthe drum, and a fan disposed within the end portion of the drumV which receives the air from the discharge opening and positively driving it over the heater and through the ldrum to again circulate through thel box.

3. A photo print drier, comprising a box having a door closing its front, and having inlet and outlet openings in opposite ends of its bottom, a partition in the rear portion of the box terminating short of the top thereof, the space between the partition and for circulating the Warm alii? through the rear of the box being in communica-tion With drum and box. 10
